While I was building my desktop, i accidently ran the screwdriver over the steel case. The scratch is small, barely an inch long and it's very hard to even see it. However it GREATLY bothers me, I don't know if I have OCD or something, but I have to get rid of it or it's going to be on the back of my mind. I've even thought of taking my entire rig apart, repacking my case and exchanging it for a brand new one. If you need to know which case I have, it's the Corsair Carbide 300r, the scratch is on the back steel part. Thanks in advance.
